5th s. of Bleddyn ap Cynfyn; acc. Powys 1116; issue: Gruffydd, Madog, Hywel, Iorwerth Goch (‘the Red’); d. 1132.
Maredudd joined in the revolt of his brothers Cadwgan and Iorwerth in 1102, but failed to change sides when they did and was handed over to the English. He escaped in 1107 and worked with his nephew, Owain. On Owain's death in 1116, Maredudd succeeded. In 1121 his raids across the English border antagonized Henry I, who led an expedition against him. He was reduced to taking refuge in Snowdonia before making peace on terms.
